I know what you mean berryboy. I'm not average size by any means. And i tend to run hotter than normal so. But i usually dont have have and excessive sweating problem unless it get above 85. You might consider wearing some better diapers like abena, secure xplus, active ultra plus, or even molicares. Ive gone ridi in an active ultra plus in 95 degree in 95 degree weather and it not bad. The liner they put on the wings do a pretty good job of wicking away moisture from sweat. Btw, I'm around 315 and I fit into large just fine.
